21 Claims.

Myinvention relates to a coin selector and slug rejecter, and means toprevent fraud by using a slug in place of a coin to operate any machine.

. I have illustrated primarily the coin selector and slug rejecterwithout showing its direct application to a coin operated machine.However, it will be apparent from this and other descriptive matterherein, that my coin selector and slug re- Jecter may be associated inany desirable manner with. such machines or devices where it isnecessary to use a coin to operate the same. The slug rejectingmechanism of my device is of a simple character and is adapted to beoperated to reject I a slug and preventit from being used to operatecoin controlled devices. The rejecting mechanism may operate to rejectthe slug before t enters the coin controlled mechanism which operatesthe device. l

A feature resides in providing a simple means for preventing any kind ofa slug from being used to operate a coin controlled apparatus, whetherit be a telephone or a machine where a coin slot is provided. Further,my selector and rejecter may be associated with any coin, operatedmechanism for dispensing goods or articles sold through a coin operatedmachine.

Heretofore, slugs of various characters have been used to operate coincontrolled devices, thereby fraudulently obtaining goods or servicethrough the use of such-slugs. These slugs have been made to closelyimitatethe coin of the denomination required and it has been almostimpossible to stop the use of the same.

others are of a disk-like nature, either having smooth faces or formedwith. printing or other fanciful configurations on the faces thereof.These last slugs which have certain representations on the facesthereof, are made to simulate a coin or to indicate that the slug is ofa certain value in merchandise or the like, but all of these slugs aremade of the proper diameter to represent a particular coin of a certaindenomination, so as to imitate the same as closely as possible. Theseslugs are often made of approximately the same weight as the coin thatthey are designed to imitate, thus making it even more diiiicult todetect them and cause the same to be rejected before they manipulate thecoin controlled device.

A feature of my invention resides in providing a coin selector and slugrejecter which is capable in the one device of detecting and rejecting aslug, whether it be smooth-faced or formed to imitate a coin, or even ifthe slug is formed with. a hole therein, and also to select the propercoin tary selector and rejecter.

been made to prevent the use of slugs, they have in a manner to retainthe same while the slugs in virtually any form are rejected. Therefore,I have provided a means with a wide range of utility in accomplishingresults which I believe have not been possible heretofore in a singleuni- While devices have failed in not having sufflcient range to preventthe use of almost any type of slu With such old devices, it was onlynecessary for the operator to carry a -variety of slugs and ifyone wouldnot work, another one would probably do so.

With my device, the operator "is not able to use these different slugs,for any slugs will be detected'and rejected so they are'worthless, andthe proprietor of a coin operated device is thereby protected in the useof the same.

Some of these slugs are formed with a hole therein, while These featuresand other details will be more fully and clearly set forth throughoutthe specificatlon and claims.

My coin selector and slug'rejecter A is illustrated as a unita ry devicecontained withina suitable casing which is provided with a top H),

end walls H and side walls" and I3. The cover lliis provided with a coinreceiving groove l4 formed in the coin tube l5.

-. The: drawings illustrate the. coin selector and;

slug-rejecter A as a unit of itself and not attached to a coin operateddevice, because it will be apparent that the same may be'attached in anysuitable manner to 'fit various different coin operated devices, so asto be of the proper size and dimensions to operate therewith. There area large variety of these devices and owing to the fact that it would notbe practical toshow themall,,I have simply shown my. coin selector andslug rejecter inits various forms and in larger detail, so as to more.clearly illustrate the operation of the same and to permit the parts tobe more readily described. I have, however, shown one application of mycoin selector and slug rejecter to an ordinary toll telephone box, asillustrated in Figure 17. r g The detector A is provided with anoperating handle I8 which operates the trip l1 to push the same forwardinto the dotted line position illustrated in Figure 3 and when theoperatin leve l6 reaches this inward position, the trip I1 isautomatically released and permitted to be forced back into its originalposition; The operating lever 16 can be then pulled out into position tobe reoperatedt As the rod 16 is pulled out, the shoulder l8 whichoperates the trip I! ratchets over the spring dog IQ of the trip IT.

The trip lever I1 is mounted upon a transverse shaft 20 and is adaptedto operate the same each time the hand lever 16 isli'orced inward. A

lever 2| is mounted on the shaft 20 and is formed with a curvedoperating end 22 which engages the end of the vacuum cylinder B. Aspring 23 holdsthe end 22 in engagement with the cylinder B. Thebackward movement of the lever 2| is'i'adjusted by the set screw 24carried in the end The vacuum cylinder B is supported by the bracket 25which is secured to the bottom 26 by the screws 21. This frame is formedwith a vertically extending wall portion 28 upon which the in extendedposition by the coil spring 3| which extends about the same, and whenthe lever I6 is operated causing the lever 2| to compress the I portion30 into the base portion 29, a vacuum is built up in the cylinder whichbecomes effective for the purpose which will be hereinafter set forth,at the moment that the'lever l1 trips oil? base portion 290i the vacuumcylinder is mountof the lug l3. This operation is of primaryim- 75portance in carrying out some of the principles of my selector, Withinthe vacuum cylinderB,

I provide a plunger 32 which is slidably supported in the vacuumcylinder and is normally caused v to be held in projected position bythe inner coil spring 33 whichengag'es in one end of the cylinder 30 andagainst the shoulder of the collar 34 inthe end of the plunger 32. Thisplunger 32 is provided with a sharp working face 35 which is adapted toengage against the coin Using in the operation of the selector A, asillustratedin Figure. '7. In thisfigure', the coin 36 is in 1305i! tionto be engaged/by the sharp working edge 35 of the plunger of the vacuumcylinder-B and the plunger is shown compressed within the vacuumcylinder while the vacuum cylinder is compressed within'the base portion29. The parts." f 1 as illustrated herein Figure 7;:show the same'just lv I prior to the moment of release ofthe lever l1 and before the vacuumcylinder B automatically is expanded by the spring 3 I. r

I have illustrated in Figure 9, a slug 3'! which is formed with an outerannular bead around the faces thereof and a central opening 31. In Fig--11De1 0, I-have illustrated a slug *38 which .is formed with smoothouter faces. In Figure 11, I have illustrated a slug 39 which is formedwith an annular bead around thesame, similar toaa coin and also formed"with printed matter there,

on'to simu'late a coin, as well as-to be provided with a numeralindicating the denomination thereof, such as 5. These figures illustratesome of the slugs that are commonly used to fraudulently operate coinoperated devices.

The coin groove is formed to'lead down to a position in axial alignmentwith the vacuum cylinder B. I provide a gate arm 40 which is pivotallysecured at 4| to the wall 28 of the bracket 25, as illustrated in Figure6. The arm 40 normally is held' in the full line position illustrated sothat the arcuated edge 42 will form a shoulder against which the coin 36or any of the slugs 31, 3B or 39 will rest when they have been insertedinto the coin. groove H. The gate 10 remains in the full line positionuntil it is automatically tripped, whereupon it moves into the dottedline I position. The tripping of the gate arm 40 takes place just priorto the tripping of the vacuum cylinder B and after the working edge 35has engaged the coin or the slug.

The gate 40 is adapted to be tripped by the bell crank lever 43 which ispivotally secured at 43' to a bracket supporting member extendingforward from the wall 28 of the support 25. This bell crank operates therod ll in a manner to is mounted on the end of the cylinder B. The plateI] engages with the coil spring 48 which in turn engages the collar 49on the rod 46, as the cylinder B is compressed inward, causing the rodIt to move the gate 40 into inoperativeposition after the working face35 has engaged the coin or the slug. As the vacuum cylinder B isreleased and caused to expand, the plate 41 engages against a coilspring 50 which is supported on the outer end of the rod and is heldthereon by the shoulder collar il adjustably secured to the end of therod 55. Thus, as the cylinder B is ex panded, the shoulders 85 will pullthe bell crank 53 back into the position illustrated in Figure 5, whichwill cause the rod II to push the gate arm .bracket sleeve 53 which issecured on the back of the wall 28. The plunger 52 is formed with awasher-like end 54 which is normally positioned counter-sunk in the wall28 and positioned centrally in line with the coin groove It so that thewasher-like end 58 is concentric with the working plunger 32 and thecylinder B, as well as be'- ing concentrically positioned to the workingedge 35 o! the plunger 32.

A rod. 55 is slidably positioned within the hollow plunger 52 and isformed with a pointed end 55 which is normally positioned within thewasher-like end 54 of theplunger'52, as illustrated in Figure 5. The rod55 is slotted at 51 and'works over a key pin 58 to limit the slidingmovement of the rod 55. An adjustable yoke head 59 is secured to theouter end of the rod 55 and is adapted to be engaged by the pin 55 whichis positioned on one end of an operating lever 5| which controls theoperation of the plunger 52 and the rod 55. The lever 5| is pivoted at52 to the supporting bracket 53 which is mounted on the back of the wall28 to hold the lever in operative position. The lever 5| is adapted tobe I operated by the rod 54 which slidably extends through the wall andwhich is formed with a yoke end 55 which pivotally and slidably engagesthe pin 55 on the end of the lever 5|. However, the end of the lever 5|which carries the pin 55 is normally held by the spring catch 51 ininoperative locked position, so that the lever 5| will not ordinarilyoperate unless this spring catch 51 is first released. The spring catch51 is pivotally mounted at 58 and is formed with a shoe end 59 which isadapted to be engaged by the rod 1|] when the rod 15 is operated. Theother end oi. the spring catch 51 is formed with a hook 1| in theexpansion of the vacuum cylinder B. This operation causes the slug todrop into the chute 16, ejecting the same out of the selector A.

' If a slug such as 38 or 35 is inserted in the coin slot M and theselector is operated by pushing the handle I 5 inward to compress thevacuum cylinder B, the working surface" of the plunger 32 will engagethe smooth portion of the slug, sealing the end of the plunger 32 on theslug, and as the cylinder B is released by the trip l1 and caused to beexpanded by the spring 3|, the vacuum in the cylinder B andin the hollowplunger 32 will be suillcient to hold the slug long enough to carry itover the division wall 15 and drop it into the chute 15. Thus, thevacuum created in the cylinder 1B is suflicient to carry anon-perforated slug" over the dividing wall 15 and drop the slug intothe ejecting chute. The working surface 35 is sharp enough to fit thesurface of the non-perforated slug and the vacuum built up in thecylinder operates to carry a slug of this character into ejectingposition. The ejecting mechanism including the plunger 52 and the rod 55is inoperative when slugs of this character without a hole are ejectedby the selector A, because this mechanism is not needed to assist in theejection of the slug, owing to the fact that the vacuum pulls the slugout of the coin slot which engages the extreme end of the lever 5|.

The rod 10 is normally held in the position illustrated in Figure 5 bythe coil spring 12 out of engagement with the end 59 of the catch 51.Then when the cylinder B is compressed, the plate 41 will engage againstthe end oi. the rod 18 compressing the spring 12 and causing the catch51 to be released from the endof the lever 5|.

One end of the rod 54 is slidably mounted in the plate 41 and anadjustable collar 13 causes the rod to be operated when the cacuumcylinder Bgis expanded, causing the yoke 55 to pull on the pin 55 andreset the lever 5| into locked posit-ion held by the catch 51. A coilspring 15 is secured to the end of the lever 5| and acts to force theplunger 52 with the rod 55 into the open end of the plunger 32 when thecatch 51 is released and the vacuum cylinder B is compressed far enoughto release the collar from the plate 41, as illustrated in Figure 'Lsoas to permit the lever 5| to push the plunger 52 inward. This permits myselector to operate to engage a slug such as 31 with a hole in it,'asillustrated in Figure 8, permitting the pointed end of the rod 55 toengage through the hole of the slug to support the same on the rod andpermit the washer end 5| to I fast enough to keep it from fallingstraight down through the coin slot and into the chute 11, which isdirectly below the end of the coin slot ll. The ejecting plunger 52 withits piercing rod remains dormant even though the catch 51 is releasedwhen operating against a closed slug or against a coin such as 35, andbefore the plunger 52 has time to be operated by the spring 14, thevacuum cylinder B has returned to nor mal position and the collar 13 hasbeen engaged by the plate 41 to prevent the lever 5| from operating. Aslight movement of the cylinder B is sufllcient to operate the catch 51.'When'the rod 55 is actuated due to a hole in the slug, however, thelever 5| has been moved out of latching position by the spring 1|. Thisis important in the operation of this mechanism of my selector A becauseit this were not true the plunger 52 might push a 'coin over into theejecting chute 18 When acoin is dropped into the slot ll, it ,will beengaged by the gate arm 40 and. held in;this selecting position untilthe lever I5 is operated, causing the working end 35 of the plunger :32to engage the surface of the same. The fact that the coin has anirregular surface like a buflalo nickel, prevents the vacuum from beingbuilt up in the cylinder B to a sufllcient extent to draw the coin overthe division wall 15. Thus, after the cylinder B isreleased, the coin 35will drop straight down into the coin chute 11 and out of the bottom ofthe selector A into position to operate a coin controlled device ortoring tht bell in a telephone box C.-

The selector units A may form 'a part of the coin box C of a tolltelephone, as illustrated in Figure 17, there being an individualselector for each denomination such as etc., if it is desired. It isalso apparent even though it is not illustrated herein, that a separateselector plunger 32 may be provided for each denomination of coin in thetelephone box C with a single operating lever such as i. and a singlevacuum cylinder B, which may be connected in a suitable manner tooperate singularly with the vacuum .directed to the coin slot whereinthe coin is dropped. The slug ejecting chute 10 may be connected to thecoin return chute ll of the coin box C so that should an operator'placea slug in any of the respective slots for the coins in the box C, andthe lever is is operated to release the same into the coin box, the slugwill be imof the cylinder 13.

My selector A' may be made in the form illustrated in Figures 12 to 16,respectively, wherein thecoin selectors E may be provided with die facesII. which are formed with virtually the identical die formation to fitthe particular coin that is adapted to be used in the coin slot ll. Theformation of the die faces 0| is more fully illustrated in Figure 18which shows the design of the die to be used in the selectors E wherethey are designed to select a buiialo nickel. The selectors E arenormally spaced apart as illustrated in Figure 12, on each side of thecoin slot l4. When the coin or bufl'alo nickel 36 is dropped into theslot ll, it is adapted to be stopped by the gate levers 82 and 82'. Thelevers 82 and 02' are rigidly mounted on the rotatable shafts II and 88'and hold the coin in selecting position. If a slug is dropped into theslot ll, it will be held by the levers 82, and I2 in the same manner. Inthis form of the coin selector A, a hand or power operating rod I8 isalso employed which operatesthetripping lever II. The lever l'l' iskeyed to the shaft 20' which extends between the sides of the casing, asillustrated in Figure 13. This shaft 20' operates to control the settingof the selectors E so as to bring them simultaneously into contact withboth sides of the coin 38 or a slug dropped into position to beselected.

A yoke lever III) is connected to the shaft 20' and extends virtuallyequally on either side thereof 'and is connected by the links 04 to thebrackets II which are positioned in staggered relation" within thecasing of the selector and rejecter A. The upper ends 86 of the bracketsare threaded to the sleeves 01 with a comparatively steep pitchedthread, so that the sleeves 81 may be rotated by the movement of thebrackets 85 after the brackets 80 have reached a predetermined point.The sleeves 81 are rotatably mounted upon the hollow shafts la, theinner end of the shafts 08 being closed at 00. The hollowshaits 00 areconnected by the tubes 90 to the respective 'to the side wall of theselector A, whereas the der is carried by the lower end of the arm 00.Figure l4sh'ows the cylinders ll expanded and at the height of theirvacuum, whereas Figure 12 shows one of the cylinders 0i telescoped withthe portion 04 slid virtually over thesleeve II. The staggered relationof the vacuum cylinders II is illustrated in Figure 15.- Guide rods 00guidethe cylinder portions 04 which form the lower ends of the bracketsII on the outside of the cylinders 0i, whereas a common guide rod 00"the selecting position for the coin or slug, as illustrated in Figure12, so that when the gate levers 02 and 02 are moved apart, if one ofthe selectors E has not removed the member or element dropped into theposition between the gate levers B2 and 02', it will drop directly intothe slug-ejecting chute 90. The slug-ejecting chute projects out to oneside of the selector A so as to discharge the slug out of the selectorwhen it drops into the chute as. I provide a coin-receiving chute 99which projects on either side of the top end of the slug chute 98, butwhich extends out in the opposite direction and is adapted to carry acoin dropped into the same, out on the opposite side of the selector Aand to deposit the coin in any suitable receptacle or in position tooperate a coin-controlled device.

Thus, when the selectors E are brought up into contact with the faces ofthe member dropped into the coin slot II and held in the positionillustrated in Figure 16, if one of the selectors E fits either facethereof, such as the buffalo of a nickel like the design illustrated inFigure 18, the selector fitting the same should act to draw the coin toone side or the other of the slug chute 98. If neither of the selectorsE select the element from the selecting position, it is a slug and itwill be left to fall straight into the slug chute 90 and be thuselected.

The faces of the selectors E which are formed with a die to fit theparticular coin which the dies are adapted to select are formed with aseries of perforations Hill to permit the vacuum set up in the cylinders9| to operate through the connecting pipes 90 and the hollow shafts 80,to draw /a coin properly fitting into the selector E by vacuum to oneside of the chute 98, so that the coin may be dropped into the coinchute 89 when the vacuum ceases. Each of the hollow shafts 88 isprovided with a hole ilil which is adapted to align with a slot I02formed along the inside of the sleeve 81, only after the selectors E arebrought together, as illustrated in Figure 14, fitting against eitherside of a coin or slug. Thus,

a vacuum in the hollow shaft 08 becomes effective through the openingsI00 on the coin fitting in the die face iii to hold the same while theselector E moves back into the position illustrated in Figure 12,whereupon the vacuum is broken or has subsided to drop the coin 36 intothe chute 09.

In operation, when the power lever lliis operated to rotate the shaft20', the yoke H0 will draw the links 84 around the shaft 20 sufficientlyto pull the brackets 05 toward-each other, bringing the selectors Eagainst the respective sides of the coin 38. After the selectors E havesliding cylinder portion 94 of the vacuum cylincome in contact with thefaces of the coin 38 1 site directions.

' aco'in chute 88. I

other similar slug which does not havethe proper and the shaft 28' isfurther rotated, the threaded (connection between the ends 86 and thethreaded sleeves 81 will cause the sleeves 81 to begin to rotate,thereby rotating the selector heads E and i rotating the die faces 8| onthe coin 38 in oppo- As soon as either of these die faces flts the coin,the coin will be rotated with the same, until the ends 88 of thebrackets 85 have moved towards each other the limit of travel inthe'operation of the shaft 28'. The threaded engagement between the ends86 and the threaded sleeves 81 is sufficient to rotate the die faces 8|of the selector heads E a complete rotation, thereby always insuringfitting the face of the coin, no matter how the coin is dropped into theslot I4. The rotation of the sleeves 8l also brings the slots I82 intoalignment with the holes IM and since the slots I82 overlap the ends ofthe hollow shafts 88 at this time, as shown in Fig. 19, communicationbetween the vacuum cylinde1's 9| and the selector heads E isestablished.

Thus, as only one side of the coin may fit the die faces 8| at a time,one of the selector heads E will draw the coin by vacuum to one side ofthe chute 88 when the selector heads E are tripped 'and moved apart.When the rotation of the shaft 28' stops by the tripping lever I Idisengaging from the operating power lever I8, the spring 81 thenoperates to separate the selector heads E and causes the rotation of thesleeves 81 and the heads E after they have moved back against thesupporting brackets I83.

In the operation of the selector heads E, the gate levers 82 and 82 arereleased from holding the coin 36 or the slug, afterthe selector heads Eengage the same. It is also apparent that the heads E hold the coin orthe slug between the same until the selector heads are separated by thetripping lever I'I. With this construction of the selector A, where thedie faces 8| are of a true formation to fit the coin, such as a buffalonickel, a dime, a twenty-five cent piece, a fifty cent piece or adollar, or any other suitable coin, or member adapted to be-used as acoin having a particular die face, it is apparent that only when theproper coin 'or member is used to fit the die, is it possible to depositthe same into the If a slug like 31, 38 or 39, or any configuration onone side thereof to fit the die face 8| is endeavored to be used in thisform of the selector A, it will not be picked up by the vacuum in one ofthe selector heads E, and thus it will be dropped the moment that theselector heads separate, falling directly into the slugejecting chute98, which rejects the slug out of the selector A.

The gate levers 82 and 82' are operated by.

meansof levers I88 and I88 which are mounted [on shafts 83' and 83,respectively, as shown in Figs. 13 and 15. The operating means alsoincludes a lever I84 (which is pivoted at I85 so as to be rotated in thedirection of the arrow, Fig. 16,

iwhen engaged by the power rod I8 near the end of its stroke. When thelever I84 is rotated in this manner, the connecting link I88 whichextends between lever I88 and lever- I88 is effective position. As thepower rod I8 is pushed against the lever I84 it opens the gate leversjust prior to releasing the tripping lever II. The mechanism operatesquickly when it is tripped and a selection or rejection is made of thecoin or slug which has been deposited in the selector A.

The coin selector and slug ejector A in this last form is positive inoperation and will operate to absolutely prevent. the'use of a slug inplace of a predetermined coin, where the die face 8| is made of the sameformation as the face of 'ie coin. Thus, the efficiency of my selectorand slug rejecter will be readily apparent, wherein it is possible forme to provide a perfect coin selector and slug rejecter, therebyproviding a means of protecting coin-operated devices with my selector.determined coin to be selected is an important feature of my inventionand insures a perfect operation in selecting the coin, as well asaperfect operation in rejecting a slug. The only way that a 'slug couldbeat'my selector would be to have the same formed with a faceconfiguration identical with that of the coin: to be selected. It willalso be apparent that my selector is very efiicient in its operation,owing to the factthat no matter which way the coin is inserted in thecoin slot I4, either one or the other. of the selector heads E will pickit up and carry it into the coin chute 98, retaining the same to operatethe coin-operated mechanism with which my selector is associated.

It is also apparent that the illustrative to describe a mechanism of thecharacter set forth and to illustrate a means of carrying out theprinciples thereof, and it is obvious that the selector can be made justas small as desired and with the parts arranged in any suit- 'ablemanner to carry out these principles of se lecting a coin and rejectingany slug of any nature-whatsoever, .therebypreventing fraud in the useof slugs.
